Hypervisor-Independent Architecture The Cisco Nexus 1000V Switch for KVM employs the same hypervisor-independent architecture used across other hypervisors (such as VMware vSphere and Microsoft Hyper-V), and has two components (Figure 1): ● The virtual Ethernet module (VEM) is deployed on each physical host managed by the Cisco Nexus 1000V as part of the KVM hypervisor. ● The virtual supervisor module (VSM) can be deployed as a virtual appliance on any KVM host or on the Cisco ® Cloud Services appliance. Figure 1. Cisco Nexus 1000V Architecture © 2014 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public Information. Page 2 of 8 Both of these components are tightly integrated with the OpenStack environment to provide operational simplicity: ● The VEM is a hypervisor-resident component and is tightly integrated with the KVM architecture. ● The VSM is integrated with OpenStack using the Neutron plug-in (Figure 2). Figure 2. Cisco Nexus 1000V for KVM Integration with OpenStack Features High Availability The Cisco Nexus 1000V Switch is designed to be resilient with high availability built into the system at multiple levels: ● Cisco NX-OS Software, the OS run by the VSM, is specifically designed for high availability at the network, system, and process levels. Critical processes run independently for ease of isolation, fault containment, and upgrades. Processes can restart independently in milliseconds without losing state information, affecting data forwarding, or affecting adjacent devices or services. ● VSMs are typically deployed in active-standby pairs for high availability. The state and configuration remain constantly synchronized between the two VSMs to provide stateful switchover if the active VSM fails. VSM and VEM communication is built for reliability. In the event of loss of communication with the VSM, the VEMs can use nonstop forwarding (NSF) to continue to switch traffic according to the last-known configuration. Enhanced Visibility with Cisco NX-OS The Cisco Nexus 1000V Switch provides advanced Cisco NX-OS features including: ● Enhanced visibility and troubleshooting of virtual machine traffic through features such as Cisco NetFlow and packet statistics. ● Simplified virtual networking operations and manageability through a strong partner ecosystem and features including SNMP, NETCONF, and syslog. ● Advanced switching and security through features such as VXLANs and ACLs. © 2014 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public Information.

  • Solving the Virtualization Conundrum
    White Paper Solving the Virtualization Conundrum Collapsing hierarchical, multi-tiered networks of the past into more compact, resilient, feature rich, two-tiered, leaf- spine or SplineTM networks have clear advantages in the data center. The benefits of more scalable and more stable layer 3 networks far outweigh the challenges this architecture creates. Layer 2 networking fabrics of the past lacked stability and scale. This legacy architecture limited workload size, mobility, and confined virtual workloads to a smaller set of physical servers. As virtualization scaled in the data center, the true limitations of these fabrics quickly surfaced. The economics of workload convergence drives compute density and network scale. Similarly, to meet dynamic needs of business stakeholders, growing data centers must deliver better mobility and its administration must be automated. In essence, virtualized networks must scale, be stable and be programmatically administered! What the Internet has taught us is that TCP/IP architectures are reliable, fault tolerant, and built to last. Why create yet another fabric when we can leverage open standards and all the benefits that layer 3 networks provide. With this settled, we can work to develop an overlay technology to span layer two networks over a stable IP infrastructure. This is how Virtual eXtensible LAN (VXLAN) was born. arista.com White Paper At Arista we work to bring VXLAN to the mainstream by co-authoring the standard with industry virtualization leaders. We’re also innovating programmatic services and APIs that automate virtualized workflow management, monitoring, visualization and troubleshooting. VXLAN is designed from the ground up to leverage layer 3 IP underlays and the scale and stability it provides.

  • Learn About VXLAN in Virtualized Data Center Networks
    Learn About VXLAN in Virtualized Data Center Networks Data centers have rapidly increased their server virtualization over the past decade, resulting in dramatic increases in agility. This, in turn, has created a demand for data center networks that are equally flexible and agile. Virtualization of the network is the next obvious step – decoupling the virtual network from the physical network makes it easier to manage, automate, and orchestrate. One common method being used today to virtualize data center networks is the use of overlay networks. An overlay network sits on top of the physical network, enabling Network overlays are the use of a virtual network of switches, routers, firewalls, load balancers, and so on. created by encapsulating This decoupling of the virtual from the physical enables fast programmatic provision- traffic and tunneling it ing of the network for any application. You no longer have to orchestrate changes over the physical network. Although relatively new to across a set of physical devices. data center networks, Creating a virtual overlay network also benefits the physical, or underlay, network, overlay networks have been used in campus which can now be a simple IP network that is concerned solely with delivering packets networks for years to carry to destinations. An overlay network adds simplicity, resiliency, and scale to the wireless LAN traffic over physical network, another reason overlay networks are gaining popularity. the wired network. Figure 1 illustrates an overlay network. From the perspectives of virtual machine 1 and virtual machine 2 (VM1 and VM2), traffic between them is taking the route shown by the dotted line, going through traditional networking devices such as switches, routers, and firewalls, which are instantiated in the hosts.
